Drupal8:如何从创建多语言菜单项。links.menu.yml链接

成功。第一links.menu.yml链接我是这样创造的:

my_menu_item_id:
  title: 'Dummy Title'
  description: 'Dummy Description'
  url: http://www.google.com
  parent: mainmenu
  menu_name: mainmenu
  weight: -100

然后我加入了我的模块 hook_menu_links_discovered_alter() 这样地:

   function mymodule_menu_links_discovered_alter(&$links) {
          $language = \Drupal::languageManager()->getCurrentLanguage()->getId();
          $links['my_menu_item_id']['title'] = 'Title:'.$language;
   }

所以我不得不采用不同的解决方案:

我没有使用钩子函数,而是将“class”参数添加到links.menu.yml链接:

my_menu_item_id:
  class: Drupal\my_module\Plugin\Menu\MyPluginClass
  title: 'Dummy Title'
  description: 'Dummy Description'
  url: http://www.google.com
  parent: mainmenu
  menu_name: mainmenu
  weight: -100

当然,我是在 my_module/src/Plugin/Menu

<?php

namespace Drupal\my_module\Plugin\Menu;

use Drupal\Core\Menu\MenuLinkDefault;
use Drupal\Core\Url;

    class MyPluginClass extends MenuLinkDefault {


      /**
       * {@inheritdoc}
       */
      public function getTitle() {

        $language = \Drupal::languageManager()->getCurrentLanguage()->getId();

        return (string) 'Title: '.$language;
      }

      public function getUrlObject($title_attribute = TRUE) {
        return Url::fromUri('http://www.yahoo.com');
      }

    }
